The first copper(0) mediated controlled radical polymerization (CRP) of methyl methacrylate (MMA) toward CF bonds onto poly(vinylidene fluoride) (PVDF) is reported with rather high activity. By avoiding the halogen exchange, Cu⁰ instead of Cu^I complexes utilized as catalyst is responsible for the significantly improved polymerization activity. Using FH decoupled nuclear magnetic resonance technique, the grafting sites onto PVDF are finely located. From this, detailed topologic information including the grafting density, average length of each side chain, along with the overall grafted content of PMMA, is detected by tracking the polymerization as a function of time. This work offers not only a facile CRP strategy based on inactive CF bonds but also a deep insight into the cleavage of F‐bearing compounds in organic chemistry.

铜（0）介导的单电子转移控制的向C的自由基聚合。聚偏二氟乙烯上的F键

据报道，甲基丙烯酸甲酯（MMA）向聚偏二氟乙烯（PVDF）上的CF键的第一个铜（0）介导的受控自由基聚合（CRP）具有很高的活性。通过避免卤素交换，用Cu ⁰代替Cu ^I络合物作为催化剂可显着提高聚合活性。使用F通过解耦核磁共振技术，可以精确地定位到PVDF上的接枝位点。由此，通过跟踪随时间变化的聚合反应，可以检测到详细的拓扑信息，包括接枝密度，每个侧链的平均长度以及PMMA的总接枝含量。这项工作不仅提供了基于无效CF键的简便CRP策略，而且还提供了对有机化学中含F化合物裂解的深刻见解。
